PHP Solution For Persistent Timeout Error

PHP Solution For Persistent Timeout Error

Perhaps you came across a message such as “Maximum execution time of 180 seconds exceeded” and went googling for a solution. The solution would probably be one of the following By editing .htaccess
php_value max_execution_time -1
By editing php.ini 
By editing your PHP code
// OR
ini_set ('max_execution_time', -1);
But even after trying all these.. you are still getting the same error. Here’s some possible reasons and solutions why.
    1. Your script is getting timed-out by Apache/LiteSpeed/Other Similar Web Server TechnologyIn your httpd.conf (in server config or vhost config), edit the TimeOut variable. The default should be 300.
      TimeOut 600
    2. Your using PHP-FastCGI or PHP-FPMThe error you are seeing is from apache’s fastcgi proxy who killed connection to php-fpm pool because your script did not outputted anything for 30 seconds.You can change idle-timeout in your apache config to extend it (cannot be 0):
      FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /run/php/php7.0-fpm.sock -idle-timeout 1800 -pass-header Authorization
    3. Apache or PHP isn’t resetting the execution time counter for unknown reasons Finally, if you still are not able to get it to work, simply try putting the code
      around different parts of your script/code. This is because each time you call set_time_limit it resets the timer / counter for the script. An example as shown below – I faced a problem with hashing large files and had to consistently make calls to set_time_limit
      $bytesToRead = 1024;
      $fp = fopen($filepath, "r");
      $ctx = hash_init('sha256');
      while (!feof($fp)) {
          hash_update($ctx, fgets($fp,$bytesToRead));
      $sha256 = hash_final($ctx);
